Lea Michele announced on Instagram that her former "Glee" co-star Jonathan Groff will be her maid of honor when she ties the knot with her fiance Zandy Reich.

"Maid of honor," Michele said Wednesday alongside a selfie with Groff.

Groff starred as Jesse St. James on "Glee" alongside Michele's Rachel Berry from 2010 to 2015.

Michele announced in April on Instagram that she was engaged to Reich, the president of women's clothing company AYR.

"I was so surprised," the actress said of Reich's proposal recently on "Watch What Happens Live."

"I kept saying, 'Stop joking around, stop joking around!' It was so great. I keep thinking it's borrowed and I have to give it back at some point," she continued about her four-carat diamond engagement ring.

Michele will be teaming up with another "Glee" co-star, Darren Criss, for a joint North American summer tour that begins in May.

The concert series will feature the pair performing songs from "Glee," Broadway and their own music.
